The new “Halo Plate” from Nitrous supply finally answers the question of how to get maximum fuel/nitrous volume while achieving complete and even distribution to each cylinder.

By using a unique stepped venturi design, aided by computer designed orifices, the high pressure of the nitrous is used to actually shear the fuel, optimizing the atomization of the fuel /N2O into the established carburetor air stream.

It is this “Halo” that creates a complete and even fuel charge that follows existing airflow, without the interruption that some “nozzle bar” type plates can cause. In addition, the venturi action of this plate increases port velocity without confusing the intake charge.
